STEAM-IBOILER APPLIANCE.

To aL- .whom it may concern:

Be'it known that I, JAMES A. RAY, a citiin the county of Sedgwick andState of vKansas, have made a certain new and useful Invention inSteam-Boiler Appliances;and-I declare the following to be a full, clear,and exact description of the same, such as will enable others skilled intheart to which it a pertains to make and use the invention, re erencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 is a side elevation of the invention, as applied and partlybroken away.

The invention consists in the novel construction and combinations ofparts, as hereinafter set forth. I i In the accompan ing drawingsillustrating the invention, designates the fire box of an ordinarylocomotive boiler, marked Q.

l is a steel shell riveted to the sides of the boiler proper belowthesan e, and extending from the fire box to the smoke flue S, suchshell forming a water purifying conipartment for the boiler feed water,and in which 1 the impurities removed. from such water are Fig. -lis asection on the line 2-2, Fig. 1.

I Fig. 5 is a detail side viewpartly broken away of the pipe connecting The invention has relation tosteam boiler i appliances, and is designed to provide means i forautomatically purifying the boiler feed water before and after it entersthe boiler, thus preventing the formation of scale upon sediment in thebottom of the boiler. The use of the invention is also designed toreiriove such scale after the formation thereof. q The impurities soremoved from the feed water are deposited in a separate compartnient ofthe boiler provided by the use of this invention, and from whence theyrequired as hereinafter' There is little pure water to be had, mostwater being contaminated with impurities,

Any other suitable form of trainer pipe may ofcourse be substituted.

E is a steam pipe connection'for the steam 4 dome R of the boiler, withthe reagent tank A, located upon the upper forward portion ofthe firebox, such pipe being provided with a valve E. B represents a horizontalpipe communicating at one end thereof with the reagent tank, and at itsopposite end having verticalbranches B, B, having communication at eachside of-the boiler with the feed water pipes D, D, at (Z, d.

The feed water pipes D, D, have connection at their outer ends with aY-form joint U, the lower branch of such joint having a threadedconnection o with a vertical pipe F [located in the smoke flue, suchthreaded porboiler shell,'besides corroding' the same and causingexpense n the way of boiler repairs. The sediment deposit in the boilerbottom also excludes the water from the steel. In

this way the boiler shell-and tubes become overheated and are liabie toblister or pocket, l

causing accidents and loss of life. A careful estimate of the' damagedone by hard tion a of the joint havinga nozzle extension Q). A shorthorizontal pipe ls. has con-- nection at one end thereof with theboiler,

preferably just above the fines and below the water level. and at itsopposite endhas a T- joint connection with the pipe F, the head of suchT-joint surrounding the tapered nozzle extension of the Y j ointaforesaid and signed to'contain the reagent or chemical permitting theentrance of hot water into the pipe F wlthoutinterference with the flowof the feed water. The pipe has connection at its lower end with a shorthorizontal pipe H communicating at its inner end with the lower portionof the waters purifying compartment, a valve h being provided at thejunction-- of the pipes F and v p The reagent tank A is strongly formedto withstand the steam pressure, and is deused-for purifying the feedwater, the

" and the hotwater in such jacket continually rising and causingcontinuation of the flow,

thus facilitating the water circulation.

- any foreign matters gravity than pipe and pass out of the purlfyingcompartsupplied to the feed water.

The strainer pipe in the water purifying compartment serves the purposeof filtering the water and prevents any current being formed in suchcompartment,which'would be likely to cause agitation of the impuritiesdeposited therein, and retard the settling of such impurities. Thisstrainer pipe being located at the highest point of the pipes J, Jconnected thereto, makes it impossible for of greater specific hot waterto rise to the strainer ment. The steam supply to the reagent tank heatsthis tank and the reagent therein, and causes the reagent to be rapidlytaken up and The suction caused by the flow of the feed water causes aflow of the reagent. This reagent'may however be supplied to the feedwater any other suitable means. The water purifying compartment I willbe located at the side of an ordinary tubular boiler and not 7 at thebottom thereof, as in the present case.
